Gene set variation analysis (GSVA), a particular type of gene set enrichment method, was used to monitor up‐down regulation of crucial pathways among 5 clusters of NKT cells, with IFN‐γ, NSCLC and Coronavirus‐COVID‐19 path‐feedbacks reset in crucial clusters synchronously (Figure 2i). Here, IFNG is linked to non-small cell lung carcinoma.
